SEEING-BEARD NEEDLE.

Specification of Letters Patent. Patented June 1%, 191'? Application filed June 8. 1818. Serial Etc. mines.

To all whom it may concern:

Be it known that I, ALBERT M. Pioneer, a citizen of the United States, residing at N orristown, Pa., have invented certain new and useful Improvements inSpring-Beard Needles, of which the following is a specification.

It is the object of my invention to pro-' vide a spring beard needle which will be free from the objection of crystallization at the bend of the nose or head, this part being relatively still and non-flexible in respect to the beard and that part of the stem which lies back of the beard, both of which portions will be flexible to bend in the act of pressing, and in knitting with tight stitches, enabling the needle to pass through such stitches without subjecting them to undue strain.

Another object of the invention is to provide for a large opening within the nose or head to permit the yarn to reeve through readily and also to allow the passage of knots and bunches.

The needle is shown in the accompanying drawing in which,

Figure 1 is a front view of a needle embodying the invention.

Fig. 2 is a side view of the new needle.

Fig. 3 is a view similar to Fig. 2 with the needle beard closed, and a tight loo-p thereon.

Fig. 4 is a view of the complete needle.

The needle at that portion back of the stem is. tapered by swaging as indicated by the full line a and the dotted line a. This tapered part at the back is slabbed ofi" or milled out after tempering, making this part, when the needle is formed, as thin as the beard 3. The cross sectional shape of this thinned back is indicated by the cross section b, and the thickness and shape bf the beard atthe corresponding height is indicated by the cross section at 0. head or nose A of the needle is circular in cross section and is of about fifteen-thousandths of an inch in diameter, while the stem back of the beard and the beard itself at the points b, c, are about ten thousandths thick. The nose therefore is stiffer than the The back or beard and during pressing the beard will bend and also the back but no bending will take place in the nose itself and therefore there will be no crystallization at this point, and the breaking ofi of the needle beard will be prevented. The nose being circular in cross section allows the yarn to reeve through it freely and it will take knots or bunches without ofiering obstruction thereto. Because both the backand heard can tier; tight knitting can be done without straining the yarn and I have shown in Fig. 3 a tight loop at d on the closed beard.

The inner or front side of the needle back,

or that portion in rear of the heard is rounded or semi-circular while the exterior of the back is fiat While as to the beard its front face is substantially semicircular and its inner or rear face is flattened.

What I claim is:

l. A spring beard needle havin a flexible back, the rear face of which is su stantially fiat, and its front face rounded, a nose of circular cross section and a beard rounded on its outer or front face and a substantially flat inner face, substantially as described.

2. A spring beard needle having the upper portion of its stern back of the beard inclined rearwardly in relation to the main part of the stem, its rear face cut away, a stiffened nose and a flexible beard, substantially as described.

3. A spring beard needle having a flexible beard, a flexible stem portion back of the beard wider than deep in cross section, and

a nose of circular cross section and nonor stem 1n rear of the beard of reduced thickness, said portion having its reel: face curved longitudinally and of minimum ehickness at a point intermediate the length v of said reduced portion or below the point of juncture of said portion with the nose of the needle, said nose being circular in eros's section and of one diameter throughout the semi-eircu1ar bend forming said ture.
